Lawmakers are invited to celebrate the nation’s infrastructure at the Natural History Museum on Wednesday.

The National Stone, Sand and Gravel Association, a mining group, is hosting a reception at the museum’s rotunda, followed by an tour of the rocks gallery at the museum.

The association has invited members of the House Education and Workforce Committee, the House Transportation and Infrastructure Committee, the Senate Environment and Public Works Committee and the Senate HELP Committee.

NSSGA is celebrating the passage of the multi-year highway bill, which the association says it hopes will help the aggregate industry grow.

“On all fronts, 2016 looks to be one of the best years for the aggregates industry in more than a decade," NSSGA president and chief executive officer Michael W. Johnson said in a statement.

“History shows that good years for the aggregates industry are also good years for America. That is a reason to celebrate,” he said.

The aggregates industry funded the creation of the museum’s rocks gallery, according to NSSGA, and the association now supports it to highlight the importance of stone, sand and gravel.

“America’s future is directly tied to the success of the aggregates industry,” the event invitation says. “If the aggregates industry is doing well, America is doing well!”

The museum’s rock exhibit has about 300,000 samples of rock specimens. Washington A. Roebling, who built the Brooklyn Bridge, was a major donor.
